ABB IGCT/IGBT Module

ABB offers two main types of power semiconductor modules for high-power applications: Integrated Gate-Commutated Thyristors (IGCTs) and Insulated-Gate Bipolar Transistors (IGBTs).

ABB IGCT Modules

• Applications: Medium and high-voltage applications requiring high power and reliability.
• Features:
  • Combine the best features of thyristors and transistors.
  • Provide fast turn-off capability like a transistor.
  • Handle higher voltages and currents like a thyristor.
• Typical Uses:
  • High-power AC drives for large motors.
  • Medium-voltage switchgear.
  • Static synchronous compensators (STATCOMs).

ABB IGBT Modules

• Applications: Lower voltage applications where fast switching speeds are important.
• Features:
  • Simpler gate drive circuit compared to IGCTs.
• Typical Uses:
  • Industrial motor drives.
  • Solar inverters.
  • Traction converters for electric vehicles.

Choosing Between IGCT and IGBT Modules

The selection between an IGCT and IGBT module depends on specific application requirements:

• Use IGCTs for:
  • Medium and high-voltage applications (above 2.3 kV).
  • High power requirements.
  • Need for fast turn-off capability.
• Use IGBTs for:
  • Lower voltage applications (below 2.3 kV).
  • Applications requiring simpler gate drive circuits.
  • Cost-sensitive applications.

Summary

Both IGCT and IGBT modules have their specific strengths and are suitable for different types of applications. Understanding your application's voltage, power, and switching requirements will help you choose the appropriate module type.
